There are? We aren't talking about feature bits, and the only known software that checks the vendor are Intel's math libraries.

  They are minor but enough to complicate things. For example Intel rejects the SYSCALL instruction outside 64-bit mode.

    Huh. A quick google says that's a feature bit and there's also an OS call to turn it on.
